STRING FOR MUSICAL INSTRUMENTS.

Application filed December 3, 1919.

To all whom it may concern:

Be it known that I, CHAnLns (inaivnn, a citizen of Russia and resident of New York city, borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improve ments in Strings for Musical Instruments, of'which the following is a specification.

Heretoforemetal strings for musical instruments, particularly the E strings for violins, have been provided with loops at one end for attachment to the tail pieces of the instrument, but, as known to me, such strings have had the disadvantages either that they break, or the loops slip with consequent varying of the tone of the strings in use, or the close coiling of the string upon itself to secure the loop produces such rigidity along the coil as to cause breaking of the string at the violin tail piece and the diameter of such coil is such that when in the customary slot of the tail piece it tends to break the latter.

The object of my invention is to provide a string having a loop at one end which shall be securely held against slipping and which shall be readily flexible to avoid breaking where bent, such as at the part located in the slot of the tail piece of an instrument, and shall be sufficiently small in diameter where the string enters said slot as not to tend to break the tail piece.

In carrying out my invention, I loop the part of the string adjacent to one end and twist together the adjacent main portion and part of the end portion of the wire that extends from the loop with a relatively long twist to render said part of the string adjacent to the loop thin and flexible, and I tightly coil the extending end portion of the wire beyond the twisted portion around part of the latter in a direction toward the loop or reversely to the direction of the twisted portion, the coiled portion on the exterior of the twisted portion serving firmly to secure the twisted parts of the wire together to prevent the loop from slipping. v

Reference is had to the accompanying drawings forming part of the specification hereof wherein Figure 1 is a plan view illustrating my improved string applied to a violin tail piece; 1

Fig. 2 is a section on the line 2-2 in Fig. 1, on an exaggerated scale; and

partly in section, illustrating my improvement.

A string 1, which may be of any suitable material, such as desired metal, at one end is provided with a loop 2 formed by bending the string back upon itself. Part of the string extending from the loop at 2 is placed along the adjacent main part 1 of the string and the said two parts are twisted together, as by holding one part of the string and rotating the other part, to produce relatively long twists at 3. For such purpose the extended part 2 beyond the loop 2 of the string may be laid along the main portion for a suitable distance, such as to point 4;, where the two parts of the string are held tightly and then the looped portion 2 may be rotated to provide the twists at 3, having relatively long windings such as illustrated in Fig. 3, which is exaggerated to illustrate the construction, although in the finished string the parts of the wire will hug closely together (Fig. 1). In Figs. 2 and 3 the twisted portions are shown spread, to illustrate their relation. After the string has been twisted as described the extended portion 2 of the string (shown in dotted lines extending from the point 4), is coiled tightly around the twisted portion for a suitable distance in the direction from the point 4, where the twists terminate toward the loop 2, as indicated by the close coiling of the wire at At the end of the coil 5 the string is severed or terminated, as at 6, for the finished article. The coiling 5 upon the twisted portion extends for a relatively short distance from the point 4 toward the loop, thereby leaving an extension of the twisted wire from the point 6 to the base of the loop at T. This construction provides a flexible twisted portion of the string relatively thin in diameter which may be readily bent when in the slot 8 of the tail piece 9 without danger of spreading and breaking the latter under strain. The coiling of the string at 5 upon the adjacent twisted portion tightly binds the twist together and prevents the twisting 3 and the loop 2 from slipping, no solder being required to secure the parts of the wire.

lVhen the string is to be used upon a violin, the loop 2 may be passed into the-slot 8 of tail piece 9 and the free part of the string may be passed through the loop, as illustrated in Fig. 2, and the end of the loop may bear against end portion of the coil or Cit winding 5 oil the wire. Since the loop does not slip the tone of the string when tightened by the usual means is retained, and the twisted portion does not cause unmusical tones by contact with the tail piece 9.

While my improved string is indicated as adapted for use as an E string for violins, it will be understood that my invention is not limited in use to musical strings, but may be used for other purposes where loops are to be formed in wires, cables or similar material, and. by the term string as used herein I intend to include such articles as specified.

Having thus described my invention, what l claim and desire to secure by Letters Patent is:

l. A string bent upon itself providing a loop at one end, two adjacent portions of the string twisted flexibly together adjacent the loop, and a portion of the string at the part of the twist remote from the loop coiled around said twist in the direction toward the loop to bind the underlying portion of the twist, the said coiled part of the string terminating at such a point along the twist as will provide said twist with sullicient space between said coiled part and the 100 to tit over a tail piece and in a slot thereo the twisted part along said space havin flexibility to readily conform to the ta piece.

2. A string having a portion at one end reversed in the form of a loop, and two adjacent portions of the string twisted together providing relatively long flexible turns for a, suitable distance along the string from the inner portion of the loop providing a free portion of the wire from the end of the twist remote from the loop, said end portion being closely coiled around the twist in the direction tmvard the loop for such a distance as will provide suflicient space of the twist uncovered by the coil to fit flexibly over a tail pie e free from the coiled portion, the twisted portion of the string in said space having greater flexibility than the portion having said coil.
